5.1 Formation

Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Claystone and Quartzite Properties

Know all about Claystone and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Claystone belongs to Sedimentary Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Claystone is Clastic whereas that of Quartzite is Foliated, Granular. Claystone appears Rough and Dull and Quartzite appears Lustrous. The luster of Claystone is dull while that of Quartzite is vitreous. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Claystone are pottery and that of Quartzite are an oil and gas reservoir, as armour rock for sea walls, cemetery markers, commemorative tablets, in aquifers, laboratory bench tops, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
